screening p-phenylenediamine antioxidants, their,recently, roadway releases of n,n′-substituted p-phenylenediamine (ppd) antioxidants and their transformation products (tps) received significant attention due to the highly toxic 6ppd-quinone. however, the occurrence of ppds and tps in recycled tire rubber products remains uncharacterized. here, we analyzed tire wear particles (twps), recycled rubber doormats, and turf-field crumb rubbers.
rubber antioxidants are defined as substances that could delay the aging of polymer compounds and prolong the service life of rubber products by inhibiting oxidation, heat, or light radiation . to date, the annual global consumption of rubber antioxidants is over 700,000 tons, accounting for about 40% of the total amount of rubber additives.
The latest development of rubber antioxidants
currently, rubber antioxidants are one of the indispensable additives in the rubber industry, they enhance the service life and reliability of the rubber product by protecting it from degradation. unfortunately, antioxidative efficiency, toxicity, and blooming/migration issues, etc., have plagued the development of rubber antioxidants.
end-of-life tire decontamination from 6ppd and upcycling nature,n-(1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd) is a ubiquitous rubber antioxidant and antiozonant that extends the lifetime of common rubber products, such as those found in tires. it.
rubber antioxidants and their transformation products
the rubber antioxidant might be released into the environment during the life cycle of tires, and especially the wear of automobile tires [60,61]. the antioxidants and tps carried by twps were transported into river or soil through runoff [ 57 , 62 , 63 ], while those in the smaller tire particles could even enter the atmosphere during the life.
manufacturer rubber antioxidant rd/tmq granulars powder for tire,a pplication: the product is particular excellent kinds of general-purpose ammoni anti-ageing agent. it particular suit to full-steel, semi-steel radial tire and it apply to many kinds of the tires, rubber tube, gummed tape, rubber overshoes and general industrial rubber products and also suits to emulsion products.

rubber antioxidants and their transformation products mdpi,antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation products (tps) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber.
ground tire rubber as a sustainable additive: transforming
managing waste tires presents a significant challenge globally, particularly in regions experiencing high temperatures and shortage of landfill sites. this issue is affecting countries like kuwait, where the abundance of waste tires is a major source of environmental and safety risks, particularly during the intensely hot summer months. this extreme heat has sparked numerous fires, leading to.
recent progress in the rubber antioxidants price,in this review, we summarized the recent advances in rubber antioxidants over the last 10 years and offered some perspectives to outline the challenges and future research directions for the rubber antioxidants. 2. brief introduction of the oxidation process and oxidation mechanism of the rubbers.
- Can a rubber antioxidant enter the environment with tire-wear particles (Twps)?
- Recently, it was reported that the rubber antioxidant N - (1,3-dimethylbutyl)- N′ -phenyl- p -phenylenediamine (6PPD or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (TWPs) [7, 8].
- Are rubber antioxidants harmful to the environment?
- However, recent studies have revealed that their transformation products (TPs) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber antioxidants and their TPs.
- Which rubber antioxidants are used in China?
- Amine antioxidants are the main rubber antioxidants produced and used in China, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants.
- How does a rubber matrix affect antioxidative performance?
- Obviously, the solubility/dispersity of the antioxidant within the rubber matrix is a key factor in determining the antioxidative performance, and the antioxidative efficiency of antioxidant increases with the dispersion state within the rubber matrix, owing to higher specific surface area available for termination of radicals.
